Preheat oven to 400 degrees F. Line 4 (12-cup) muffin tins with paper liners, or generously grease, and set aside.
Combine flours, baking powder, sugar and salt in the bowl of a mixer. Thoroughly mix on low speed, add the cheese and continue to mix on low until the cheese pieces are well coated and separated.
In a separate bowl, whisk together the eggs, milk and oil. Add the wet ingredients to the dry, mixing on low speed until just combined; the batter will be lumpy. Fold in the pears.
Use a #16 scoop to fill the prepared muffin tins with the batter, filling the cups about 2/3 full. Bake 20 minutes or until golden brown. Remove the pans from the oven and turn the muffins out onto a rack immediately to cool.
